Last evening I noticed a round red glow. It was coming from southwest sky. At first I thought maybe it was a fireball or comet or meteorite. But it had no tail and did not burn out. It kept moving across the sky, right overhead and then proceeded to the eastern sky. It was completely silent and moved slowly, enough time for me to yell out to my neighbors and have them too, witness this unusual event. We all concluded it must be UFO. It finally started to get smaller and appear to move outwards disappearing beyond the clouds.
